Having a compact cooler is nice and all, but cooling performance is what really matters. To test this out I employed the might of an 8-core, 16-thread Ryzen 7 1700 CPU. The processor was tested at stock, 3.55GHz, and 3.75GHz. The Furmark CPU burn in utility was used to push all cores to 100% load. Overall I was very impressed by the coolers performance. It handled the 65W Ryzen 7 1700 without much issue at all. I was even able to do a substantial overclock without even coming close to the thermal limit. This is a testament to both the efficiency of Ryzen 7 chips, and the quality of the cooler.

Preguntas frecuentes

Can the NH-L9i be used on AM4?

The NH-L9i has been designed for the Intel LGA115x platform. While it can be installed without any problems on most AM4 motherboards using the NM-AM4-L9aL9i kit, it is possible that it may not fit in some cases. Therefore, please be extra careful when installing the NH-L9i on AM4 and verify that the cooler doesn’t press against any other components.

Please also note that there has been a minor revision of the NH-L9i heatsink in April 2013 (see illustration below). Since this revision, the heatsink features a cut-out on one side in order to provide better clearance for tall motherboard components. If you install the cooler on an AM4 motherboard that has tall components close to the socket and if your heatsink has the cut-out, you can orient the cooler in such a way that the cut-out is above the components in order to maximise clearance. Regardless of whether or not your heatsink has the cut-out, please carefully double check that it doesn’t press against any components!

Which Noctua CPU coolers are compatible with AMD AM4 (Ryzen)?

The following models include a mounting-kit for socket AM4 and are thus compatible out of the box:

NH-D15 SE-AM4
NH-U12S SE-AM4
NH-L12S
NH-L9x65 SE-AM4

NH-U12DX
NH-U12DX 1366
NH-U12DX i4
NH-U9DX i4
NH-U9DX 1366
NH-U9DO (Note that the A3 version is not compatible!)

The following models are not compatible with the AM4 socket and can not be upgraded:
